COLOR-CHART.

To all whom it may concern:

Be it known that I, OSCAR A. Fons, a citior device for finding harmonic colors or color combinations for the use of artists, (1 orators, painters, and others desiring a si ple and convenient means for facilitating the selection of color or tint combinations.

The object of the invention is to provide a color chart of this character which shall be simple of construction and efficient in operation. I

The'invention consists in the combinations and arrangements of parts all as will be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a top plan view of a color chart and mounting therefor embodying vmy invention, Fig. 2 is a central vertical section of said mounting showing the chart mounted thereon, Fig. 3 is a detail central section of the chart, Fig. 4 is a bottom plan view of the chart as shown in Fig. 1, and Fig. 5 is a plan view of a mask used in combination with said chart.

The preferred form of construction as illustrated in the accompanying drawings comprises a circular mounting 1 having a disk base 2 and a pair of circular steps 3 and 4 serving as supports for the color chart and mask therefor respectively. A central pin 5 is provided on the base 2 to serve as a journal for rotating the chart 6 and mask 7. The chart 6 is composed of a plurality of disks which are secured together in operative relation by means of a thimble or eyelet 8 and about which said disks are adapted for independent rotation.

The ends of the eyelet 8 are turned over or riveted on circular knobs 9 by means of which the chart is readily handled in placing the same on the pin 5. Disks 10, 11, 12 and 13 of the chart 6 are of increasing size, or so formed that the peripheries of said disks are all visible when positioned on the thimble 8. The independently rotatable disks 14, 14', 14", 14", 14" arranged un- S pecification of Letters Patent.

der the disk 13 and constituting the under side of the chart 6 bear broken colors as will be described hereinafter. The top side. of the chart 6 as shown in Fig. 1 bears primary and secondary colors and intermediate shades, except the central disk 10 which bears tertiary colors as shown in Fig. 1.

The mask7 consists of two independently rotatable disks 15 and 16, the former being of smaller size than the latter in order that the peripheries of both disks shall be rendered visible. In order to readily rotate the several color disks independently of each other, a small perforation 17 is provided in each disk for the reception of a pencil or other small tool adapted for this purpose.

As aforesaid, the lower side of the color chart 6 bears brole n colors except disk 13 which bears pure colors. In order -to select desired combinations of colors from this portion of the chart, the several disks may.

be so rotated that the desired tints or colors shall come into close relation or in the same radius of the chart. If the desired combination cannot be found in this manner the mask 7'is resorted to which is placed over the chart as shown in F ig, 4, as indicated by dotted lines in Fig. 2. It is understood that when the mask 7 is placed over the chart 6 for comparing the colors as shown in Fig. 4, that said chart is so placed on the pin 5 that the lower side thereof as shown in Fig. 2 shall be uppermost. Having thus arranged the chart 6 and the mask 7 thereon, the desired colors may now be selected by rotating the mask 7 upon the chart. The disk 17 of the mask 7 comprises a segmental opening 18 which is adapted to render visible any sector of the chart as shown in Fig. 4. The disk 15 is provided with a segmental opening 19 in its periphery adapted for juxtaposition or registration with the segment 18 and thereby render the latter operative. By rotating the mask 7 upon the chart as shown in Fig. 4 with the openings 18 and 19, as illustrated in Fig. 5 any I staggered about the surface thereof which pared. The mask 7 is readilyrotated by are adapted to expose portions of the chart sectors at varying distances from thecenter pm 5.

It will be seen that when the openings 20 at the left of the mask 7 is brought into registration with the opening 18 that two colors or tints will be exposed to view on thedisk 14 the one at the periphery thereof:

being concealed. If the colors thus exposed are not satisfactory then the disk 15 may be so rotated that the next two openings 20 at the right shall be in registration with the opening 18, it being clear that by thus rotating the disk 15 that the portion of the disk 14 which was concealed will now be brought into view. By further rotating the disk 15 other combinations will be broughtto view by means of the other segmental openings 20. In this manner a large number of combinations of broken colors shown on the chart as illustrated in Fig. 4: may be commeans of the knob 9 provided thereon and it is secured to the disks 15 and 16by means;

of the eyelet or thimble 8.

The color chart as illustrated in Fig. 1 comprises primary, secondary and interme diate colors on the peripheries of the disks ll, 12 and 13 as aforesaid. In order to select a combination of colors for any particular purpose, one color is first selected in the periphery of the disk 13. Then the disk 12: is so rotated relatively to the disk 13 as tov bring the colors into successive registration with the color already selected. After a color has been chosen to combine with the first chosen color then the same is placed in.

the same radius and allowed to remain there until another color has been chosen. The third color is chosen by rotating the disk 11 in a manner similar to that of the disk 12, the desired combination being in this manner brought into the same radius or sector of the chart. The colors are so arranged upon the several disks that when a certain harmonic value has been reached in one seetor that the same harmonic value obtains in the other sectors. Thus if the colors exposed in one sector do not meet the requirements then the operator has the assurance that the same harmonic relation or value is presented in the other sectors so that any one of the other sectors may be chosen if desired.

The mode of operation is as follows: As-

' green, all that is necessary is to so rotate the disks that the desired shades of these colors shall be brought into the same radius or sector of the chosen yellow. In this manfirst selecting some shade of red in the large disk 13 as shown in Fig. 4. Then select a broken color from some other sector on the chart, and then another from another radius or sector. Place the mask 7 over the chart and rotate the same until the segmental opening 18 registers with the chosen shade of red. Then the disk 15 of the mask 7 is so rotated. that any one of the three pair of segmental openings 20 shall be brought into juxtaposition with the opening 18. I In this manner all possible combinations are brought to view. For four color comparison the em ployment of the openings 20 is not necessary, the only requirement being that the segmental notch or opening 19 shall be brought into registration with the opening 18, whereupon all four colors of all sectors of the chart may be readily compared.

A color chart as set forth is simple of construction, and eflicient in operation.

While Ihave illustrated and described. the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire' to avail myself of such variations and modifications as come within the scope of the appended claims.
